Question

新ViewController弹出的弹出窗口.overCurrentContext
从弹出窗口视图中有2个带有导航按钮，用于另外2个视图。
一个简单的动作，例如print很好，但是当我尝试以编程方式（从xib文件，popUpViewController）进行搜索时，什么也没发生。
```
let vc = RegisterEmailViewController.instantiate()
vc.coordinator = self
navigationController.pushViewController(vc, animated: false)
```

从任何其他角度来看都很顺利。怎么了？

PopUpViewController代码：

import UIKit

class ViewController: UIViewController, Storyboarded {
    weak var coordinator: MyCoordinator?

    @IBAction func dismissPopUp(_ sender: Any) {
        dismiss(animated: false, completion: nil)
    }

    @IBAction func buttonEmail(_ sender: Any) {
        let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "EmailViewController") as? EmailViewController
        self.navigationController?.pushViewController(vc!, animated: true)
    }

    @IBAction func buttonPhone(_ sender: Any) {
        let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "PhoneViewController") as? PhoneViewController
        self.navigationController?.pushViewController(vc!, animated: true)
    }

    override func viewDidLoad() {
        super.viewDidLoad()
    }

}

有MyCoordinator会初始化所有导航，并且不能让我自己简单地进行搜索/导航。

var childCoordinators = [Coordinator]()
var navigationController: UINavigationController

init(navigationController: UINavigationController) {
    self.navigationController = navigationController
}

因此，对控制器的引用解决了该问题。可以导航到一边，直到调用新的子视图为止。

在这种情况下有效的代码：

    let vc = RegisterEmailViewController.instantiate()
    vc.coordinator = self
    navigationController.pushViewController(vc, animated: false)

结论。很简单，有两种方法：

删除所有依赖项和其他使用 UINavigationController
仅通过新方法进行声明以供全局使用。

Swift NavigationController推送方法请求在PopUp视图中不起作用
